Summary
A large, asymptomatic meningoencephalocele was discovered in a patient with a history of thyroid eye disease. This rare condition developed after orbital decompression surgery, highlighting a potential complication.
Area of Science:
- Neurosurgery
- Ophthalmology
- Skull Base Surgery
Background:
- Thyroid eye disease (TED) can necessitate surgical interventions like orbital decompression.
- Orbital decompression surgery aims to alleviate intraorbital pressure and improve function in TED patients.
- Potential complications include bony defects and cerebrospinal fluid (CSF) leaks.
Observation:
- A 71-year-old woman with a history of TED presented with an incidentally discovered skull-base mass on neuroimaging.
- The patient had undergone prior bilateral orbital decompressions and strabismus surgery.
- No neurological symptoms were reported by the patient.
Findings:
- The skull-base mass was identified as a large, asymptomatic meningoencephalocele.
- This represents the first reported case of a meningoencephalocele following orbital decompression surgery.
- The meningoencephalocele was associated with bony defects at the skull base.
Implications:
- This case highlights a rare but significant potential complication of orbital decompression surgery.
- It underscores the importance of recognizing and monitoring for delayed complications, even in asymptomatic patients.
- Further research may be warranted to understand the incidence and management of post-surgical meningoencephaloceles.

01:26Brain Abscess l: Introduction
A brain abscess is a focal, intracerebral infection characterized by a localized collection of pus within the brain parenchyma, resulting from microbial invasion and the body’s inflammatory response. It progresses through stages: early and late cerebritis, followed by early and late capsule formation, reflecting tissue destruction, immune response, and eventual encapsulation.Etiology and PathogenesisCausative organisms vary with source and host factors, often involving polymicrobial infections,...
01:22Cerebral Edema ll: Pathophysiology
Vasogenic edema is a major form of cerebral edema characterized by abnormal accumulation of fluid in the brain’s extracellular space due to disruption of the blood–brain barrier (BBB). The BBB is a specialized structure composed of endothelial cells connected by tight junctions, supported by astrocytic endfeet and a basement membrane. Under normal conditions, it tightly regulates the movement of ions, proteins, and solutes between the bloodstream and brain parenchyma. When this barrier loses...
01:14Increased Intracranial Pressure l: Introduction
Intracranial hypertension is a sustained elevation of intracranial pressure (ICP) above 22 mm Hg. In supine adults, normal ICP is ~7–15 mm Hg.The rigid, nonexpandable cranium contains three components—brain tissue, blood, and cerebrospinal fluid (CSF)—that total ~1,700 mL in a typical adult: 1,400 mL brain (~80%), 150 mL blood (~10%), and 150 mL CSF (~10%). According to the Monro–Kellie doctrine, total intracranial volume is effectively fixed. When one component expands, CSF and venous blood...
01:29Increased Intracranial Pressure ll: Pathophysiology
Increased intracranial pressure (ICP) refers to a potentially life-threatening rise in pressure inside the skull. This usually happens when there is a major change in the volume of brain tissue, blood, or cerebrospinal fluid (CSF) — the three components inside the skull. According to the Monro-Kellie doctrine, if the volume of one component increases, the volumes of the other components must decrease to maintain normal pressure. If this does not happen, ICP rises.The process often begins with...
01:19Cranial and Spinal Meninges
The cranial and spinal meninges are complex protective structures surrounding the central nervous system (CNS), consisting of the brain and spinal cord. These meninges consist of the dura mater, the arachnoid mater, and the pia mater. They protect the CNS, provide structural support, and aid in circulating cerebrospinal fluid (CSF).
Cranial Meninges
These meningeal layers cover the cranium. The dura mater is the outermost layer of cranial meninges. It is a thick and durable membrane of dense...
